COMPOSITION OF MATTER AND PROCESS OF MAKING SAME.

Specification of Letters Patent.

Application filed May 24, 1906. Serial No. 318,562.

Batented April 23, 1907.

maybe in the form of dextrine' in any of its V forms, ordinary starch or flour.

My invention comprises further the method or process of making this improved composition of matter.

In the manufacture of cellulose or pa er pulp under what is known as the sul 'te processf, which consists in boiling Wood and other fibres underpressure in a solution containing sulfurous acid and a base, such as.

lime or magnesia, a vast quantity of a watery mixture known as Waste sulfite liquor is produced that hitherto has had little value, besides being highly objectionable in a num ber of ways and very difiicult of disposal. In carrying the method or rocess of my present invention into effect, em loy a concentrated or evaporated solution o the same; preferring to use a neutral, undecom osed and concentrated mass of this waste iquor made in accordance with a method I have developed for utilizing such material. In my Patent, No. 833,634, dated October 16, 1906, I have set forth a process of treating I this raw waste liquor, by rendering it substantiallyneutral with theaid of-milk of lime or other suitable alkaline material, and then quickly concentrating such neutralized body in vacuo, without decomposition, to a desirable density.

In the preferred method or rocess of making my improved compoun I propose to use this substantially neutral, undecomposed and concentrated mass of sulfite liquor made in accordance with the process above set forth, and to a quantity of this liquor at a density of about 30 B., I add a certain quantity by volume of molasses, and a certain quantity by volume of-a watery solution or paste of starchy material, which may be made from dextrine, flour or ordinary starch. The watery solutions or astes of the starchy material, whether of extrine, flour and starch are, approximately, in the proportion of about two and one-half (2 1/2) pounds of the dry form of suchmaterial to'about four (4) quarts of water, and they are prepared by cooking or in any other desirable manner.

I have discovered that a combination of the in edients herein set forth is highly valuab e as an adhesive and that the starchy material may be in the form of flour of the various grades, dextrine or starch of the vari-,

ades, all of these materials Working equa ly well.

There is this difference, however, that the proportions of the various ma.

terialsused will vary, depending upon the form of the starchy material used. For instance, when dextrine is combined with the sulfite liquor and molasses,.I may use substantially equal parts by volume of said. ingredients. The sulfite liquor is of a density of 30 B., the molasses is of the ordinary or common grade, the cheapest on the market, and the dextrine employed is from a solution or paste of the same in the proportions above set forth. When flour is used in place of the dextrine, however, the pro ortions, by volume, are substantially as fo lows: sulfite liquor, 30 parts, molasses, 30 parts, flour paste, 40 parts. When starch is used there is again a difference, and in this form of my improved composition of matter, the pro ortions, by volume, are substantially as fol ows: sulfite liquor, 40=parts, molasses, 35 parts, starch paste, 25 parts.
